Machining process and apparatus for machining

A method of determining a tool path to machine a component, the method comprising the steps of:

• securing the component to a fixture having a zero point alignment datum, the component and the fixture having respective mobile reference points;
• aligning the fixture mobile reference points to target reference points on a machine tool;
• aligning a digitized model of the component to the component mobile reference points;
• determining the position of the component on the fixture from the component mobile reference points and the fixture mobile reference points;
• and adjusting a nominal tool path for the machine tool dependent on the position of the component,
• wherein the nominal tool path is adjusted before the fixture is located on the machine tool.
